Frequently Asked Questions
What is the format of SOPEEC Fourth Class Part 4A?
SOPEEC specifies 100 multiple-choice questions per paper and three hours in most jurisdictions. Ontario’s October 2024 TSSA guide still describes 150 questions in 3.5 hours, so Ontario candidates should confirm their booked sitting directly with TSSA. Use only the references and calculator permitted by the administering authority; approved full code volumes are not universally prohibited.
What is the passing score?
SOPEEC specifies 65% on each Fourth Class examination paper. A candidate pass rate is a different statistic and is not published here.
Who administers the examination?
SOPEEC publishes the common syllabus and examination framework. Provincial and territorial authorities administer examinations and issue credentials under their own requirements.
How do Papers 4A and 4B differ?
Part 4A covers applied sciences, legislation, safety, environment, materials, piping, electricity, controls, communication, boiler construction and boiler systems. Part 4B covers further plant equipment and operation, including pumps, water treatment and heating/cooling subjects. Both papers and jurisdictional certification requirements must be satisfied.
What are the eligibility and certification requirements?
Requirements differ by authority. ABSA lists approved education routes for examination eligibility, including completion of the relevant A portion for Paper A; TSASK describes the examination as entry level with no examination prerequisites. Certification has separate education and operating-experience rules. Have the authority assess your actual course and experience records.
What does the examination cost?
There is no single Canadian fee. ABSA’s schedule effective November 1, 2026 lists CAD 117.40 per examination. TSSA’s schedule effective May 1, 2026 lists CAD 89 for a scheduled examination, with applicable HST and any other applicable charges. Check the authority’s current schedule before paying.
How do retakes and passed-paper validity work?
The administering authority sets waiting periods, reapplication rules and the period for completing certification. Do not apply another province’s retake interval or certificate-renewal policy to your application.
